In the works for almost four years, reporter Kevin Donovan's five-part series "Death in a Small Town" explores the death of a child and the turmoil it plunged his family into. Nathaniel McLellan was 15-months-old and acting strangely at his daycare when his parents, Rose-Anne and Kent McLellan, were summoned to take him to the hospital. What followed was a tumultuous journey of a seemingly tunnel visioned investigation, conflicting medical reports and a family's ongoing fight for justice. Kevin Donovan joins "This Matters" to discuss the story and add some personal commentary to the investigation.
